The purpose of the research: to develop the scientific and technological foundations of the processes of pyrolysis-carbonization and activation of products obtained from lignocellulosic raw materials, including forestry waste, to obtain multifunctional and low-cost specialized sorbents (activated biochar) that differ in parameters of the nanostructured matrix and surface chemistry, evaluation of the effectiveness of their use in the removal of inorganic and organic compounds from the aqueous phase - typical water pollutants. Research methods: determining the influence of the main properties of the source material and modes of heat treatment processes on laboratory, pilot plants and on industrial equipment; sorption studies in equilibrium conditions. The criteria for the selection of raw materials from biologically renewable resources are substantiated. Data were obtained on the methods and conditions of pre-treatment of wood raw materials by means of pyrolysis-carbonization, dry and wet cooling, drying of the wet product. New conceptual principles of energy-saving technology for obtaining biochar (BС) and activated BС with heat treatment of BС in two stages and activation of the product in a fluidized bed with steam are proposed, which significantly reduces the activation time and minimizes the consumption of energy resources. It was established that wet cooling of BC makes it possible to vary the surface chemistry of the carbonized material. The adsorption capacity of BC samples to remove typical pollutants from water was evaluated and it was established that they already have a basic porous structure, which is characteristic of AC and is not inherent in wooden BC. The adsorption capacity of the studied samples is close to the activity of commercial AC CAD. Application: water supply and water treatment Product Description popup.authors Yezlovetska Inna S.
